Auto off problem after lollipop update

[Cyrus1]

Hi guys recently i updated my xperia t2 ultra to lollipop and from then on my device has totally become useless. Everytime i turn on my phone it automatically gets off in a few minutes. After doing some research on the internet i ve found out that its not only me having this problem. I request sony to fix this as soon as possible maybe with another update.
Others having the same problem may also join this thread.

I have a T2 Ultra running lollipop and I haven't experienced this problem, repair the phone with PCC and report back

Do you have the correct SIM card size? do you experience the same if you boot on >> safe mode

[Cyrus1]

Yes i do have the correct sim size. Yes the problem persists in the safe mode too. Prior to the update the device was working fine.

Let's narrow down the problem,  could you try to repair your phone again with PCC ? also remove both SIM and SD cards, does it reboot?

I hope it works

It isnt working . Updating a phone and especially a sony device is really a dangerous task it seems, it totally ruined my device.

Remove both SIM and SD cards, do you experience any bootloops?
